IPA-TENT OFFICE I OF HOLBORN, LONDON ENGLAND I GAS-LIGHTER Application filed April 26, 1928, Serial No. 272,980, and in Great Britain May 3, 1927.

T This invention relates to gas-lighters of the kind comprising an approximately bell shaped part provided with means for igniting coalor similar gas, and its primary ob- .ject is to provide improvements whereby the gas-lighter is rendered of greater service and more convenient in form than hitherto, while afurther object is to facilitate the use of such lighters and the recharging of the same for ensuring the operation of the igniting means.

According to the invention, the bell shaped orequivalent part of the gas-lighter contains within it the igniting means and is adapted to serve as a gas collector in close proximity to the gas burner whereat the gas is to be ignited. The bell shaped part may also be adapted to serve as a base or support for the gas-lighter. The igniting means consists of an exposed electric element or wire rendered incandescent by an electric current supplied from an electric dry cell or battery in circuit therewith. Preferably, the electric cellor battery is enclosed in a metal container connected with the bell shaped part and provided with a metal lid or other hinged or removable portion formed with an aperture capable of fitting over a metal knob or projection extending from one end of the said cell or battery and forming one of the terminals thereof. The knob or projection is a working fit in the aperture and makes electrical contact with the said lid or portion, while the other end of the electric cell or battery is provided with a terminal capable-of beingmoved into contact in opposition to spring pressure with an electric contact connected by an electric lead with one end of the said electric element or wire, the opposite of which is'connected with the metal container. For completing the electric circuit and rendering incandescent the electric element or wire, pressure is applied to the knob or projection Whichserves as a press button and the said cell or battery is moved thereby and the terminal on the opposite end thereof is moved into engagement with the said electric contact.

I11 order that the said invention may be clearly understood and readily carried into' thin platinum wire and isfitted with a perforated plate 0 which serves to partly enclose the space within the bell shaped part and render it capable of collecting a supply of gas from a gas burner for ensuring its lgnition with the air Within the space upon the wire being rendered incandescentv The bell shaped part a is of metal and is provided with the upstanding metal container d closely fitted with the removable lid 6 in which 'the aperture f is formed. Within" the container d is disposed the electric bat:

lery 9 provided at its upper end with the projecting metal knob terminal 72. which projects throughthe aperture and makes electrical contact with the lid 0, and at its lower end with a plate terminal 9' capable oi being moved into engagement with the contact stud 7r; upon pressure being applied to the knob h and the resistance to move ment of the said battery. by the rubber spring cushion Z being overcome. The rubber cushion which is of tubular form not only serves as a spring but alsoas an electrical insulator and thereby avoids any possible shortcircuiting of the electric current which might possibly take place where a metal spring is employed. The rubber cushion is also more easily secured inplace, such as by an adhesive to a discm arranged at the lower end of the container d, than bya metal spring. In the said disc m is also mounted the said stud k and is thereby held in position in contact with a second stud n to which is connected one end of the platinum coil 6 the other end being secured by an electric lead to the bell part a. The stud n is fixed in a second disco of cardboard or other insulating material and is thereby held out of contact with the metal in which '55 formed an opening 2) through which the stud 72- projects. The electrical'circuit in this construction of gas-lighter when the knob terminal 71 is pressed is from the electrical battery through the plate terminal j, studs and a, platinum coil Z) and electric lead to the bell shaped part a, container cl, lid 0 and knob terminal 7.: oi the battery. The handle 9 facilitates using the device enabling a person to hold it by the lingers of the hand Whilst using the thumb for applying pressure to the knob 71 The alternative construction shown in Figures 3 and 4; is similar construction to that previously described with the exception that the bell shaped part is substituted by a sleeve member ct termed with a perforated forward end portion a which permits the passage of to and from the sleeve member a While the open end thereof enables coal gas to pass into the said member a and to mix with the air in proximity to the coil Z of platinum wire which connected in a similar manner to that already de scribed with the electric battery excepting the electric connection between the stud A: and the coil 6 and this connection is cl"- fected by the headed pin 0' one end of which is connected to the coil 1) and the other end formed with the head is arranged in contact with the stud 7c. The pin 7" is disposed in the tubular part 8 and is maintained centrally of the sleeve member a by the disc 0. The device described with reference to Figures 3 and l is adapted to be clasped in the hand by the container part (Z.

What we claim and desire to secure by Letters Patent of the United States is 1. A gas lighter comprising a metal casing, an electric battery within and movable longitudinally of said casing, a projection from one terminal of the battery extending through an aperture in an end wall of the casing and being constantly in electrical connection with said wall, a metal stud supported within the casing beyond the other terminal of the battery and insulated from the casing, yielding means of non-conducting material. normally holding the adjacent battery terminal from contact with said stud, and a resistance wire having its ends connected respectively to the metal casing and said stud.

2. A gas lighter comprising a metal casing, an electric battery within and movable longitudinally of said casing, a terminal at one end of the battery being in constant electrical connection With the casing, a partition of insulation material extending transversely across the interior of the casing beyond the other end of the battery, a metal stud supported by said partition in position to contact with the other terminal of the battery when the latter is moved from its normal position, resilient means normally holding the battery out of electrical contact with said stud, and a resistance wire having its ends connected respectively to the metal casing and said stud.

3. A. gas lighter comprising a metal casing, an electric battery within and movable longitudinally of said casing, a projection from said battery extending through a wall of the casing and constituting a means for bodily moving the battery in the casing, one terminal of the battery being in constant electrical connection with the casing, a metal stud supported in and insulated from the casing, said stud being in the path of niovement of the other terminal of the battery, a compressible member of insulating material within the casing normally preventing contact between said stud and cooperating battery terminal, and a resistance member having its ends respectivel connected to the metal casing and said stuc.

l. A lighter comprising a metal casing, an electric battery Within the casing, said battery having at one end a knob-like terminal which extends through and is in constant electrical connection with an end wall of the metal casing and having at its opposite end a plate-like terminaha stud supported within the casing and insulated therefrom in alignment with said plate-like teriiinal, yielding means normally preventing contact of the plate terminal and said stud, and a resistance member having its ends respectively conected to the metal casing and said stud.
